7 Claims.

This invention relates to safety razors, and refers more particularly to single-piece safety razors adapted to carry double-edge razor blades.

In my co-pending U. S. patent application Serial Number 149,050, now Patent No. 2,264,323, dated December 2, 1941, I have described a safety razor having two clamping members which may be moved through the central opening of a double-edge razor blade by the manipulation of the stem or handle portion of the razor to clamp this blade upon a resilient support which is carried by a frame element.

An object of the present invention is to improve and simplify the construction of a safety razor of this type.

Another object is to eliminate the necessity of manipulating the razor handle by utilizing a separate clamp for actuating the clamping members.

. Other objects of the present invention will become apparent in the course of the following specification.

in accomplishing the objects of the present invention it was found desirable to provide a safety razor having two arcuate clamping members which are preferably connected with two levers by a pin-and-slot connection, the two levers being engaged by clamping means tending to maintain the arcuate clamping members in their op erative blade-clamping positions. A compression of the-clamping means .will actuate the levers and cause them to withdraw the arcuate clamping members into their inoperative positions, thereby facilitating theremoval of a razor blade and the mounting of a new blade upon the projecting ends of the clamping members.

The guard serving as a counter-support for the clamped blade may be fixedly attached to the frame guiding the arcuate clamping members, or'the guard may be made of two parts connected to separate levers and movable therewith when the levers are swung outwardly to their inoperative positions by the compression of the clamping means.

The sharp edges of a razor blade mounted upon the razor may be covered by concave elongated covering elements which are pivotally mounted upon the corresponding edges of the guard.

The metal parts of the razor are of such light weight and the handle of the razor may be inflated and/or made of such light material that the razor will float when dropped in water. The

handle is provided with one or more suction cups which make it possible to attach the razor coneniently to any horizontal, vertical or inclined surface. Thus the safety razor constructed in accordance with the principles of the present invention is particularly suitable for shaving while its user is taking a bath in a bath tub.

The invention will appear more clearly from the following detailed description, when taken in connection with the accompanying drawings showing, by way of example, preferred embodiments of the inventive idea.

In the drawings:

Figure 1 shows in side elevation a safety razor constructed in accordance with the principles of the present invention, in its clamping position;

Figure 2 is a transverse section through the head of the safety razor, in its inoperative position;

Figure 3 is a top view of the safety razor;

Figure 4 shows the safety razor partly in front elevation and partly in section;

Figure 5 shows in transverse section the head of a safety razor of a somewhat different construction;

Figure 6 is a side elevation of the head of the razor illustrated in Figure 5;

Figure 7 is a top view of the razor shown in Figures 5 and 6;

Figure 8 illustrates a different razor head in its clamping position;

Figure 9 shows the razor head illustrated in Figure 8 in its inoperative position.

' Thesafety razor shown in Figures 1 to 4 of the drawings comprises a handle I0 which may be hollow and/ or filled with a light-weight fluid and which may be provided with a number of suction cups ll (Fig. 1) for attaching the razor to any suitable surface, such. as the edges of a bath tub.

The head of the razor includes a U-shaped frame l2 having a transverse piece l3 which is firmly connected to the handle I!) (Fig. 4) and twolegs or frame posts l4 and having convex top surfaces I6 and IT, respectively (Figs. 1 and 2). The frame post I4 is provided with an arcuate slot l3, while a similar slot i9 is formed in the frame post l5.

A rod extends between the frame posts M and I5 and is used as a pivot rod for the levers 2| and 22 which actuate the clamping members 23 and 24, respectively. Two guide rods 25 and 26 also extend between the posts I4 and I5 and have top surfaces which constitute a continuation of the surfaces It and ll of the posts [4 and IS. The lower arcuate surfaces 21 and 28 of the guide rods 25 and 26 constitute guides over which the clamping members 23 and 24 slide. The guide rods 25 and 26 are separated from each other by a space 29 through which the clamping members 23 and 24 extend.

The lever 2! which is sim lar in shape to the lever 22, has a downwardly extending fingen engaged portion 32, a sleeve mounted on the rod 2i), an intermediate portion a transverse portion 33 extending through the slots I8 and i9, and upper posts 34 provided with slots against the other, so that the levers 2| and 22 are maintained by the clamps 39 in the operative position shown in Figure l. I

The lever 2| is connected to and movable along with a frame-like guard portion 40. A similar guard portion 4| is connected with the lever 22.

In the clamping position shown in Figure l, the guard portions 49 and 4| form a substantially continuous blade-supporting surface; so that a blade 42 may be conveniently clamped between the guard portions 40 and 4| and the clamping members 23 and 24.

A concave elongated finger-protecting element 43 extends along the outer edge of the guard portion 40 and is pivoted at 44 thereon. The member 43 hangs downwardly in the inoperative position of the razor shown in Figure 2. However, after the clamps 39 have moved the parts to the operative clamping position shown in Figure l, a sharp edge of the blade 42 may be conveniently covered by the member 43 which is swung upwardly about its pivots 44. The Opposite sharp edge of the blade 42 may be covered by a similar finger-protecting element 45 which is pivoted at 46 to the outer edge of the guard portion 4|.

The arcuate clamping members 23 and 24 are similar to each other in form and may be resilient either totally or in part. The members 23 and 24 which extend through the space 29 between the guides and 26, have clamping edges 47 and 48, respectively. In the inoperative position shown in Figure 2, the clamping edges 41 and 48 are situated one next to the other, so that a blade 42 may be conveniently placed upon these edges which will extend through the central opening 49 of the blade. As soon as manual pressure upon the finger-engaging lever portions and 36 is released, the pressure of the clamps 39 will move the levers 2| and 22 toward each other. The clamping member 23 is connected with the lever 2| by pins 50 which are' integral with the member 23 and which extend through slots provided in the posts 34 of the lever 2|. Pins 5| which are integral with the clamping member 24, extend through slots 38 provided in the posts 31 of the lever 22. Thus a movement of the levers 2| and 22 toward each other will swing the clamping members 23 and 24 about the guides 25 and 26 and will move them through.

the, control opening 49 of the blade 42 until the.

edges 41 and 48 of the clamping members will engage the blade 42 and press it firmly against the guard portions 49 and 4|, thereby clamp-1 ing the blade.

The operation of the razor is apparent from the above description. The clamps 39 normally hold the parts of the razor in the operative clamping position shown in Figure 1. In order to move these parts into the inoperative position shown in Figure 2, the user merely presses the finger-engaged lever portions 30 and 36 toward each other. The levers 2| and 22 then swing away from each other while being guided in the slots I8 and I9, and the guard portions and 4| move along with the levers 2| and 22. Since the clamping members 23 and 24 are connected with the levers 2| and 22 by the pins 59 and 5|, the levers will cause the clamping members to swing about the guides 25 and 26 and to withdraw through the central opening 49 of the blade 42 and the space 29 into the interior of the frame I2 until the clamping members reach the position shown in Figure 2.

Then the used razor blade may be conveniently removed and replaced by a new one.

As soon as manual pressure upon the lever portions 39 and 36 is released, the clamps 39 will move the razor parts back to the clamping position shown in Figure 1.

The safety razor shown in Figures 5 to '7 of the drawings has a handle 69 which is firmly connected with a U-shaped frame 6|. The frame 6| has a transverse piece 62 and two frame posts 63 having concave top surfaces 64 and arcuate slots 95.

A pivot rod 65 is carried by the posts 63 and carries the levers 67 and 68. Two guide rods 69 and I9 also extend between the posts 63 and are used as guides for the clamping members 'II and I2.

The levers 6! and 66 are similar to each other in form and have finger-engaging portions 13, transverse portions !4 extending through the slots '65, and upper posts I5 provided with slots I6. The levers 61 and 68 are pressed against each other by arcuate resilient clampsTI.

In this construction, the guard or support I8 is made of one piece and is firmly connected to the frame posts 63 by screws or the like which are located substantially in the middle of the posts 63. The support I8 is curved and its radius is slightly greater than that of the curved surface 64 so that at the outer edges of the posts 63 the support I9 extends at a little distance from the surfaces 64. Due to this arrangement, the blade 42 is resiliently supported upon the razor.

Concave elongated finger-protecting elements 19 extend along two outer edges of the support I8 and are pivotally connected herewith. The members 19 are used to cover the sharp edges of the blade 42 when the razor is not being used.

The arcuate clamping members II and I2 are connected by pins with the levers 61 and, respectively. The pins 80 are firmly connected with the clamping members and extend through the slots 76 of the levers 61 and 68.

This razor is operated in substantially the same manner as that previously described. However, in this construction the blade support or guard I8 does not participate in the movement of the levers 61 and 68, since it is firmly attached to the frame 6|.

The safety razor shown in Figures 8 and 9 of the drawings has a handle which is firmly connected with a U-shaped frame 9|. The frame 9| carries two pivot rods 92 and 93. A lever 94 is mounted on the pivot rods 92, while a similar lever 95 is mounted on the pivot rod 93.

The lower ends 96 and 91 of the levers 94 and 95 are maintained away from each other by the prongs of a spring 98 which is connected at 99 to the frame 9|. The upper ends I90 and IIJI of the levers 94 and 95 are provided with slots I02 through which the pins I93 extend. The pins I03 I04 and I05. A guard or blade support I96 is firmly connected to the frame 9| and carries finger-protecting elements I 01.

The operation of this razor is similar to those previously described. In this construction, the

are carried by the clamping members.

levers 94 and 95 swing outwardly about separate pivots when the spring 98 is compressed by manual pressure against the lever portions 96 and 91.

It is apparent that the specific illustrations shown above have been given by way of illustration and not by way of limitation, and that the structures above described are subject to wide variation and modification without departing from the scope or intent of the invention.
